This is a 2 panel commission. The first panel can be much smaller than the second, whichever looks best.
1st Panel:
Copy the reference image with the two choices and the black background, except replace the text with:
"Spank Natsuki"
For the first box, and
"Let Natsuki spank you"
For the second box.
Then have a mouse cursor hovering on the "Let Natsuki spank you" option as if it is about to be clicked.
2nd Panel:
The background is the classroom image. Natsuki (Pink haired female) is sitting down on one of the chairs clothed while MC (Male) is naked and bent over her lap. She is currently spanking him with 'slap' sound effects near her hand. His butt is red and his erection is pressed against her leg. Natsuki and MC are both blushing with flustered expressions.
Natsuki has a speech bubble that says "Do you have a b-bon...?"
MC has a speech bubble that responds with, "N-no!"
MC and Natsuki both share a *thought* bubble with the text, "Why am I enjoying this?!"
